Comparison of Structure and Viability of Block Cartilage Grafts With Ultrafine Diced Cartilage Grafts in Rabbits.

ABSTRACT:

Background

Autologous block cartilage grafts are traditional and commonly used but have an incidence of warping of 39%. Autologous diced cartilage does not warp or require a long learning curve and can be made from a combination of cartilage sources. Ultrafine diced cartilage (UFDC) (<0.5 mm³) facilitates cartilage nutrition owing to its increased surface area and reduced diffusion distance. An ultrafine size reduces the risk of irregular graft contours.

Methods

Randomized pre- and posttest experimental studies on rabbits (Oryctolagus cuniculus). The fixed variables were block and ultrafine diced cartilage grafts. The dependent variables were structure, viability, and collagen content 1 month after implantation.

Results

There was significant warping
